Bitcoin Core Introduces New Security Disclosure Policy

- A new Security Advisories page has been added to the Bitcoin Core website. It currently documents disclosures for versions of Bitcoin Core prior to v0.21.0. All of these versions are End of Life (EOL) and no-longer receive any maintenance updates. The latest release of Bitcoin Core is v27.1. The 26.x and 25.x branches also both continue to receive maintenance updates.

- Later in July we will disclose all vulnerabilities fixed in Bitcoin Core version 22.0. In August, all vulnerabilities fixed in Bitcoin Core version 23.0. And so on until we run out of EOL versions to disclose vulnerabilities for."
